Application filed I une 3, 1912.

To all fav/rom it may Concern:

Be 1t knownthat I, WILLIAM A. DYEP., a

i citizen of :the United States, residing at duced.

a sectional vieu/,on the linev 5 5 of Fig. 3.

Vestal, in the county Vof Broome and State orNeW York, have `invented certain new and useful.improvements in Incubatore, of

which the following is a specification, ref

.erence being had to the accompanying drawings.

rlhis invention relates to new and useful improvements in iireless incubators and more particularly' to a hot Water incubator, the object of the invention being to provide an incubator of this character wherein suicient heat is produced byradiation from a sut'l'icient volume of Water retained at a hot Water at proper intervals. A

Another object of the invention is to pro- Avide ahot Water incubator wherein a perfeet system of ventilation is assured and also the proper amount .of moisture profurther object of the4 invention is the provision of an incubator of this character which will possess advantages `in points of eiiiciency and durability, isfinexpensive to manufacture and at the same time is simple 1n construction and operation.

- With the above and other objects in view,l p the invention consists in the novel lfeatures of construction and the combination and arrangement of parts hereinafter more fully -described, pointed vout in the claim, and

invention. Fig. 2 is a top plan View, the' cover beingremoved to show the interior thereof. Fig. 3 is a longitudinal'sectional View taken on the line 3 3 of Fig. 6, the

left hand` end thereofbeing taken on lines.

3 -3 of Figs. 4 and 6. Fig. 4 is a sectional view on the line 4-4 of Fig. 8. Fig. 5 is Fig. (i is a Jfragmentary horizontal section taken on the line. 6-6 of Fig. 3.

Referring more particularlyT to the drawings, 1 indicates the body of the incubator` suitably supported by means of the standards 2. AArranged Within the body adjacent the bottom thereof are the egg'trays 3 which are suitably supported by means,y of the cleats 4 secured to the side Wall and the `Central guide member 5. Arranged Within specificati@ f Letters Patent.

the casing and disposed directly vabove the egg trays is a suitable tankut having outwardly extending ianges '7 formed at its ends and side edgeswhichare adapted to rest upon the cleats Sto support the tank. y

The walls of 'the body are provided with a dead an' space 9 and an exhaust space 10. The tank is so arranged in the body as to leave an air spacell bettveen the top of the, tank and the top of the l pipe to close the same when not in u e. Y proper temperature by the introduction ot of the posite directions lengthwise of the tank and returning to and through the same-Wall. then down through the dead air spaceito point beneath the tank. The pipes then extend through the Wallof the egg chamber to conduct the heated air in the egg cham-l ber,l the Warml air being diffused' down through andaround the eggs so that oxyfgen is taken in by the eggs, the vsame being very essential to the proper development of embryo. After the Warm air has circulated through the egg chambers, the same passes down through the exhaust openings 15 and is then conducted through the air passages 16 and openings 16a to the exhaust passages 16 where the same is passed off up through the openings 17 and 17, 'said latter openings being closed by means of the slid ing shutter members 18 arranged upon.- the body. The inlet openings 14 are closed by means of the shutters 18. y

A drawof pipe 19 extends transversely through the side Walls of the body and into the tank -nearthe bottom thereof to draw oit' the Water when the same becomes cooled.

Arranged at the end of the tank" opposite the pipe 19 is an emergency outlet -pipe 2O to be used in case an inexperienced operator has too much heat caused by putting in too rauch heated Water. Y

It Will be seen that the exhaust openings 15 in the bottom or the egg chamber are thereof The air then passes in one end of the pipes 15, said pipes extending in op g egg chamber is extremely simple. As the 46 of the drawings indicates the line uponr which the uppermost bottom member of the double bottom is sectioned in Fig. 3 of theV drawings. It will be readily seen that the means for supplying heated fresh air to the fresh air passes in through the openings 14, it is conducted up through the space 16 and then enters one end of the pipes 15 which extend lengthwise of the tank on the-top thereof and return to and through the same wail andthen down through the air space 6 to a point beneath the tank. These pipes 15 are heated by means of steam .and hot' air escaping from the tank through the pipes 21 which extend upwardly and out throughthe top of the tank from a point near the bottom thereof.

Sufiicient moistureis supplied to the egg lchambers by means of the short pipes 22 having one end opening into the space l11 above the tank and the other end of lsaid pipes extending outwardly into the air space 6, thence downwardly and into the egg chamber at a point above the trays 3. An air vent 23 is formed in the top of the tank and is closed', when not 1n use, by means of Y the plug which extends through' coinciding openings in the top of the body.

From the above description taken in connection with the drawings, the use, advan- ,l tages, and operation of my improved incu- "wie bator will be readily understood and it will be apparent that I have provided a tireless lincubator wherein a perfect system of ventilation is assured andthe proper amount of Vmoisture is obtained at all times.

While have shown and described the preferred formvof my invention, ikwill ob vious that various changes inthe details of f construction" and in the `proportions -may be resorted to vfor successfully carrying my i11-` -vention into practice .without lsacrificing any .of the novel features or departingffrom the t c scope thereof. n
